NUT-LOCK.

Specification of Letters Patent.

Application filed April 29, 1911.

Patented Oct. 3, 1911. Serial No. 624,043.

To all whom it may concern:

Be it known that I, JOHN W. WINGETT, a citizen of the United States ofAmerica, residing at Washington, in the county of lVashington and Stateof Pennsylvania, have invented certain new and useful Improvements inNut-Locks, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention relates to nut locking devices and the objects of myinvention are to furnish a bolt with positive and reliable means in amanner as will be hereinafter set forth for looking a nut upon a boltwhereby it cannot become accidentally displaced, and to provide a nutlock that can be advantageously used in connection with rail joints,bridges, rolling stock and structures subjected to vibrations that havea tendency to displace nuts.

Other objects of my invention are to provide a nut locking device thatcan be cut and stamped from a single sheet of metal, and to afford meansfor looking a nut that can be manipulated by unskilled labor.

Further objects of my invention are to provide a nut lock that can beused in connection with the present type of nut, and to accomplish theabove results by an inexpensive and durable device.

I attain the above objects by a mechanical construction that will behereinafter specifically described and then claimed.

Reference will now be had to the drawing, wherein Figure 1 is alongitudinal sectional View of the nut look in accordance with thisinvention. Fig. 2 is a side elevation of the same. Fig. 3 is a similarview showing the nut locking device in another position. Fig. 1 is aplan of a blank nut locking device, and Fig. 5 is an end view of the nutlook.

A nut look in accordance with this invention is made of malleable metaland is cut or stamped from sheet metal to form a fiat body 1 havingdiametrically opposed lateral extensions 2 adapted to be bent upon thedotted line 3 into parallelism to engage the opposite facets 4 of a nut5.

The body 1 is provided with a slot 6 at the lower edge thereof, theinner end of the slot terminating centrally of the body and this slot isadapted to provide clearance for the screw threaded end 7 of a bolt 8.The slot 6 is of sufficient depth whereby the body 1 will be concentricrelatively to the bolt upon which it is mounted.

The upper edge of the body has a malleable narrow tongue 9 adapted to bebent at the upper edge of the body into parallelism with said body, thetongue 9 having the end thereof tapered, as at 10 and said tongue is ofa sufficient length that the lower end thereof will extend below thelower edge of the body 1. When mounting the washer upon a bolt, thetongue 9 is adapted to pass through a vertical opening 11 providedtherefor in the end of the bolt, said tongue preventing the washer fromrotating and the lateral extensions of said washer preventing the nut 5from rotating. The lateral extensions are of a suflicient length toengage the facets of the nut 5 even though the washer is positioned somedistance from the nut, and the exact location of the washer depends uponthe location of the opening 11. As shown in Fig. 1 the opening isadjacent to the end of the bolt and as shown in Fig. 3

the washer is reversed whereby the tongue thereof can extend through anopening cent to the inner threads of the bolt 8.

It will be noted that the tongue is bent inwardly between the lateralextensions 2 and between the body and the nut, and it is in thisconnection that I reserve the right to bend the tongue outwardly uponthe outer side of the body 1.

With the device made of malleable metal it can be removed by resortingto the use of a suitable instrument and it can be again used or untilthe lateral extensions are broken by being bent back and forth.

lVhile in the drawing there is illustrated a preferred embodiment of theinvention, it is to be understood that the structural elements aresusceptible to such variations as fall within the scope of the appendedclaim.

What I claim is A nut lock comprising the combination with a bolt havingthe threaded end thereof provided with an opening and a nut mounted uponsaid threaded end, of a washer mounted upon the bolt and comprising abody having the lower portion thereof pro- Vided with a slot for thereception of said extending through the opening of said bolt bolt,oppositely disposed lateral extensions to prevent turning of the Washer.10 carried by said body bent to engage with op- In testimony whereof IafiiX my signature positcly disposed facets of the nut to prein thepresence of two Witnesses.

vent the turning of the latter upon the JOHN WV. WINGETT. washer atongue carried by the upper por- Witnesses:

tion of said body and bent downwardly into MAX H. SRoLoVITz,

parallelism with respect to said body and CHRISTINA T. H001).
